We add the scale factor to each length of an image to get the scaled copy.<br> -True or False?
Anit [1.1K]

Answer:

false

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

original dimensions / scale of the drawing  = dimensions of the scale drawing

To scale an image, divide the original length by the scale

for example the length of the image is 100 and the scale factor is 4

the length of the scale copy = 100/4 = 25

The slope of two lines are 5/6 and 2/p. determine the value of p that will make the lines
Anni [7]
Parallel:  the lines have = slopes.  We thus need 5/6 to equal 2/p.  then 5p must equal 12, and p = 12/5.   (answer)

Check:  Is 5/6 = 2 / (12/5)?  YES

Perp.:  The lines have slopes that are negative reciprocals of one another.

Then -6/5 = 2/p,  or

 -6      2
---- = ----
  5      p             Thus, -6p = 10, and p = -5/3   (answer)

A machine with velocity ratio of 5 is used to raise a load with an effort of 500N . If the machine is 80% efficient , determine
Yanka [14]

Answer:

Solutions given:

Velocity ratio V.R =5

effort =500N

efficiency =80%

magnitude of load=?

mechanical advantage [M.A ]

we have

efficiency =M.A/V.R*100%

80=M.A./5*100

80/100*5=M.A

M.A.=4

again

we have

M.A =load/effort

4=load/500

load=500*4

load=2000N

<h3><u>the magnitude of the load is 2000N</u>.</h3>

15. Bhargav stops in at a deli to get lunch for
Colt1911 [192]

Each roast beef cost $4 and each vegetarian sandwich cost $2.5

Let x represent the cost of each roast beef and let y represent the cost of each vegetarian sandwich.

Bhargav buys five roast beef and three  vegetarian sandwiches and the order costs $27.50. This can be represented by the equation:

5x + 3y = 27.50     (1)

Bhargav buys 2 roast beef and 6  vegetarian sandwiches and the order costs $23.00. This can be represented by the equation:

2x + 6y = 23.00     (2)

To find x and y, we have to solve equation 1 and 2 simultaneously. Multiply equation 1 by 2 and subtract equation 2 from the result:

8x = 32

x = 4

Put x = 4 in equation 2

2(4) + 6y = 23.00

6y = 15

y = 2.5

Therefore each roast beef cost $4 and each vegetarian sandwich cost $2.5
